Hi karan karan,

The http.STATUS_CODES is an object that holds a collection of all the standard HTTP response status codes and a short description for each. For example, http.STATUS_CODES[404] === 'Not Found'. In the video is Reggie using this to make it print the description of the error so it becomes more readable to the user 🙂

Thankyou Rohald van Merode, for the explanation. Is it only an overview course? as Reggie used a lot of words like Modules and require, streams and all but they were not explained. Will we be diving a bit deeper ahead?

At 2:03, you are showing an if clause, but you have cut the video and omitted adding the curly braces {} to wrap the code part in.

It should be

if (response.statusCode == 200) {

}

and not just if (response.statusCode == 200)
